Engineered chemical biomimetic technology is a technique that uses biomolecules or structures to imitate the functions or properties of living organisms, which can be applied in nanodelivery systems to improve drug targeting, biocompatibility, stability and safety. The application of engineered chemical biomimetic technology in nanodrug delivery systems mainly includes the following aspects:

Cell membrane biomimetic: This is a technique that encases natural cell membranes around the surface of nanoparticles to give nanoparticle cell membranes characteristics, such as long circulation, immune escape, adhesion, and homologous targeting. Cell membrane biomimetic technology can use different types of cell membranes, such as red cell membrane, platelet membrane, white cell membrane, cancer cell membrane, to achieve different drug delivery purposes.
